(4) The close contacts between the confirmed cases and asymptomatic infected persons are red team during the centralized isolation medical observation period of 14 days, for example, all the nucleic acid tests are negative within 14 days, and all the nucleic acid tests are negative during the home health monitoring period of 15-2 1 day, 2/kloc.
(5) Close contact between confirmed cases and asymptomatic infected persons, and close contact between suspected cases and suspected cases are red team during the period of centralized isolation medical observation.
